Kathryn Matlack, an assistant professor of mechanical science and engineering, recently became a faculty affiliate at the Beckman Institute. She will collaborate with members of the Molecular Design and Engineering research theme. She is the principal investigator for the Wave Propagation and Metamaterials Laboratory that seeks to understand how waves propagate in complex materials over several length scales. The knowledge can then be used to design efficient and multi-functional materials, structures, and devices.
